Introducing REF_XDP701_4800 hot-swap controller solution for next gen AI server architectures

As the world of artificial intelligence (AI) continues to evolve, the demand for more powerful and efficient data center and server applications is on the rise. In response to this growing need, Infineon introduces a hot-swap controller board level solution, specifically designed for future ±400/800V AI data center and server applications. The introduction of ±400/800V architecture in AI data centers and servers marks a significant shift towards higher voltage systems, enabling faster and more efficient data processing. Infineon addresses the unique challenges of high-voltage systems with the REF_XDP701_4800.

The REF_XDP701_4800 reference board is a comprehensive hot-swap controller solution designed to support the growing demands of next generation ±400/800V power architectures in AI server applications. It features the XDP701-1 hot-swap controller and CoolSiC™ JFET technology, providing a robust and reliable solution for protecting systems against power-related failures.

The XDP701-1 hot-swap controller is a key component in AI data center power delivery systems, protecting against inrush current and other power-related failures such as over/under voltage and over temperature. The XDP™ controller works in conjunction with the 1200V-rated CoolSiC™ JFET technology, which supports inrush current control and pre-charging of large input bulk capacitance. This technology provides a good balance of RDSon*A figure of merit and robustness, making it suitable for hot-swap applications.

The REF_XDP701_4800 reference board offers a range of technical features, such as:

  • Wide supply voltage range of 100 VDC to 800 VDC (±10%)
  • Output voltage of 800 VDC (±10%)
  • Output current of 0 A to 16 A
  • Up to 12 kW of output power delivery
  • Pre-charge up to 300 μF of input bulk capacitance in less than 2 seconds
  • Real-time telemetry via PMBus v1.3
  • Closed-loop SOA control
  • Support for 0V/+800V and -400V/+400V DC Bus

Key benefits:

  • Ability to control the CoolSiC™ JFET in a linear mode, allowing the power system to operate safely and reliably during over-voltage events
  • Advanced protection and monitoring features including energy and power reporting enable designers to optimize their system design for reliable and efficient operation
  • Integrated auxiliary supply
  • Fast pre-charging of input capacitance

The REF_XDP701_4800 reference board is designed to support the growing requirements for power path protection solutions in high-power AI server ecosystems. By providing a robust and reliable solution for hot-swap controllers, Infineon aims to help developers create efficient and scalable AI server applications. This solution can help reduce the risk of power-related failures, improve system uptime, and lower operational expenses. With its compact dimensions of 193 mm x 93 mm, the REF_XDP701_4800 reference board is an ideal solution for space-constrained AI server applications.
